how to force speed on 3c905b-tx nic under SCO 5.0.4 - SCO

I've read the article where it says to change the space.c file with a valid speed from the space.h file..... but can someone sell me exactly how to do that? in other words, what will the new space.c file look like? if it currently says: short e3H_Media_Override[4] = { MEDIA_OVERRIDE_DEFAULT, MEDIA_OVERRIDE_DEFAULT, MEDIA_OVERRIDE_DEFAULT, MEDIA_OVERRIDE_DEFAULT }; then what will it look like once I force it to, let's say, 100 half or 10 half? Do I put those numbers at the end of the lines as shown in the space.h file? Thanks, Larry Rekow _ _ _ _ _ _ _ _ ...

    Default how to force speed on 3c905b-tx nic under SCO 5.0.4

    I've read the article where it says to change the space.c file with a
    valid speed from the space.h file.....

    but can someone sell me exactly how to do that? in other words, what
    will the new space.c file look like?

    if it currently says:

    short e3H_Media_Override[4] = {
    MEDIA_OVERRIDE_DEFAULT,
    MEDIA_OVERRIDE_DEFAULT,
    MEDIA_OVERRIDE_DEFAULT,
    MEDIA_OVERRIDE_DEFAULT
    };

    then what will it look like once I force it to, let's say, 100 half or
    10 half? Do I put those numbers at the end of the lines as shown in
    the space.h file?

    Thanks,

    When I was running a 10bT network, all was well. We've moved,
    and I'm now running a switched network with a 10/100 switch.

    The ability of the 3com card to autonegotiate is not very good,
    and I'm getting about a 25 percent packet loss. I'd like to force the
    NIC to a certain speed in hopes of clearing this up. Oddly enough,
    there is no packet loss within the lan, only for people connecting
    via the internet. So something is messed up...my other servers
    here experience no packet loss at all, wan or lan.

    Thanks for your advice, I'll try it tonight and see if things
    clear up.
